Kate Upton may have found a new boyfriend – “Dancing With The Stars” dancer Maksim Chmerkovskiy.

The New York Post writes that supermodel Upton, 21, and Chmerkovskiy, 33, were seen on a dinner date at the New York restaurant Catch on Monday.

Sources said they openly held hands after avoiding photographers at a premiere for the HBO documentary “Casting By,” which they both attended – and to which Upton made headlines by wearing a black dress with sheer, underboob-revealing panels.

Upton wore a nude bra under the dress to show off her curves.

“They seemed pretty open about their relationship,” a source said of Upton and Chmerkovskiy.
